"Moving parts in rubbing contact require lubrication to avoid excessive wear. Honorificsand formal politeness provide lubrication where people rub together.Often the very young, the untraveled, the naive, the unsophisticated deplore theseformalities as "empty," "meaningless," or "dishonest," and scorn to use them.No matter how pure their motives, they thereby throw sand into machinery that does notwork too well at best."--Robert Heinlein in "The Notebooks of Lazarus Long"
